Question

a polynomial function has four turning points and two zeros. it’s degree could be ___? select all that apply 4567

Answer 1

6

Explanation:

edge 23

Answer 2

A polynomial function with real coefficients has four turning points and two zeros could be a degree 6 or any higher even degree because a polynomial with degree n has at most (n - 1) turning points.

So, it cannot be a degree 4.

It cannot be a degree 5 because it has two real zeros, and then three complex roots. A polynomial function with real coefficients cannot have an odd number of complex roots.
